The imagePROGRAF iPF6450, 24-inch large format printer was designed for professionals in the graphic, fine art, photography and proofing markets that seek the highest possible standards for quality-control and image reproduction. An incredibly large color spectrum is produced by the 12-Color LUCIA EX pigment ink set, which also provides better scratch resistance and smoother gradations. The new Multi-sensor included with this printer provides improved color density detection and allows for a full calibration to be completed within 15 minutes, with the ability to use non-Canon branded media. A new Color Calibration Management System allows for color calibration targets to be created using the iPF6450 with optional spectrophotometer and shared across all new iPFX400 12-color printers, and the included software allows for all printers on the network to be monitored from one central location. The printer supports ink tank sizes of 130ml and for the first time, 300ml, and the new sub-ink tank keeps some ink in reserve to allow for tanks to be changed without interrupting a print. In the printer's highest print mode, the order of ink application and layering is optimized to maintain the highest print quality with fewer passes, making this mode twice as fast compared to previous models. The iPF6450 is also equipped with a large 250GB hard drive, geared to increase productivity in high volume printing and streamlined workflows, while allowing for faster processing of large files as well as the ability to reprint jobs directly from the printer.
